ORIGINS: UNIVERSE, LIFE, HUMANKIND, AND DARWIN

Information

We debate origins of the Universe, life, Earth, humans, religion, atheism, using common sense, evolution, cosmology, geology, archaeology, and other sciences, to repel biblical creationism and other religious beliefs.

While smoke from wildfires can cause local cooling, just like aerosols from coal plants and pollution, that effect isn't large enough in extent or time to initiate an ice age. There was one period that your observation does bring to mind. 360 Million years ago oxygen levels got quite high, and global wildfires ended it, leaving a distinct charcoal layer in sediments.
